CROWN  COPPER  AND   SULPHUR  MINE. 


Dear  8ir: 

I  beg  leave  to  call  your  attention  to  the  follovring  reporta  and 
estimâtes  relating  to  the  Crown  Copper  and  Bulphur  Mine,  which 
show  that  ingot  copper  can  be  produced,  transported  and  sold  for 
ten  and  one-third  cents  a  pound,  in  quantities  that  will  pay  a  net 
annual  profit  of , , ,. $95,000  00 

And  that  sulphur  can  be  produced  and  marketed 
at  a  cost  of  six  dollars  a  ton,  and  showing  an  annual 
profit  of ^y 66,000  00 

Making  a  total  of $161,000  00 

If  you  will  take  the  trouble  to  read  the  following  pages  you 
will  be  prepared  to  consider  the  value  of  the  mine  as  an  invest- 
ment,  on  the  terms  set  out  at  the  close  of  this  letter.  'Çbe  re- 
ports are:  Smk.

DESCRIPTION  OF  THE  CROWN  MINE  BY 
R.  G.  LECKIE. 

The  Crown  Copper  Mine  is  situsted  in  the  township  of  Ascot, 
province  of  Québec,  and  ia  distant  from  Sherbrooke  about  eight 
miles.  The  Passumpsic  River  Railroad  skirts  the  property,  Ca- 
pelton  station  l)eing  less  than  a  mile  distant,,  thus  furnishing  di- 
rect connection  with  the  tv'hole  railroad  system  of  the  Northern 
States.  The  Qrand  Trunk  Railroad  passes  within  a  mile  and 
a-half  of  the  mine,  furnishing  means  of  transport  to  Portland 
Québec,  Montréal  and  the  Western  States. 

The  velns  or  beds  of  côpper  ore,  upon  which  the  mine  is  lo- 
cated,  hâve  been  opened  on  at  varions  points  over  a  distance  of 
two  miles.  The  Hartford  Mine,  adjoining  this  property,  bas  l)een 
worked  by  the  Canada  Sulphur  and  Copper  Company  (linaited), 
of  Glasgow,  and  yielded  a  monthly  product  of  from  1,500  to  2,000 
tons  ore,  averaging  nearly  flve  per  cent.*  copper  and  thtrty  per 
cent,  sulphur.  Th|s  ore  was  treated  without  further  sorting  by 
the  Henderson  Process,  which  extracted  the  copper  in  the 
hûmid  way.  ' 

No.  5  shaft  on  the  Hartford  Mine,  from  whieh  the  whdle 
supply  of  ore  was  drawn,  was  started  on  the  surface  fQur  hun- 
dred  and  seyenteen  feet  from  the  Une.    It  foUows  the  dip  of 

*The  Laboratoir  Bookof  the  Canada  Copper  ahd  Salphar  Company  ahowa 
the  average  percentage  of  the  ore,  exclusive  of  the  rich  ores  plcked  ont  and 
Bhlpped  to  Bngland,  dnring  the  laat  six  months  the  Hartford  Mine  waa

the  ore-bed  (frbm  tWeûty-fl?e  to  forty  degrees  (25  ^  to  40  °  ),  and 
bas  been  sunk  to  a  depth  of  flve  hundred  and  tbirty  feet, 
which  carriea  it  fifty  feet  beyond  tbe  dividing  line  between  tbe 
Crown  and  Hartford  Mines.  Tbe  présent  stopes  at  the  line  of 
the  Crown  Mine  are  225  feet  in  lengtb,  and  average  from  six  to 
thirty  feet  in  width,  of  solid  ore,  with  s  very  decided^prove- 
ment  of  quality  in  the  lowest  levels,    \  „ 

Tbe  ore  is  a  sulphuret  of  copper  and  iron  (copper  and  iron 
pyrites),  and  averages  five  per  cent  copper;  but  at  severai 
points  the  copper  contents  rise  to  ten  and  even  twenty-four  per 
cent.  *    ,; 

AU  of  tbe  ore  contains  a  notable  amount  of  silver,  the  distri- 
bution of  wbich,  ïk  the  Iode,  is  irregular,  running  from  three 

i 

ounces  to  thirty  ounces  per  ton.  Dr.  Harrington,  Cbemist  of 
tbe  Gteological  Burvey  of  Canada,  reports  tbat  he  bas  found  over 
seventy  ounces  in  the  gray  arsenical  ore.  A  parcel  of  forty  per 
cent,  matte,  shipped  to  Eogland,  contained  two  bundred  and 
twenty  ounces  silyer  per  ton,  by  àssay  made  there. 

If  tbis  ore  should  be  smelted,  ail  the  silver  would  be  concen- 
trated  in  the  matte,  and  could  be  saved. . 

Beveral  trial  sl^y^bavè  been  sunk  upbn  tbe  Crown  Mine,  and 
considérable  surftJMpcplorations  made,  proving  even  a  larger 
developement  of  oré'bearing  ground  than  on  tbe  Hartford. 

The  ore  from  the  Hartford  Mine  is  being  raised  and  deliv- 
ered  at  the  Works  at  an  average  coet  of  sixty-three  and  six-bua- 
dredtbs  cents  per  unit,  equal  to  two  and  three-quarter  cents  per 
pound  of  fine  copper  contents.  The  cost  of  extracting  tbe  cop- 
per from  the  ore  by  the  Hunt  &  Douglas  process,  and  running 
the  precipitate  into  ingôt  copper,  is  estimated  by  Mr.  Douglas

the  sllver  is  8av«d,  and  thls  will  1^  found  suflflcient  to  pay  the 
cost  of  mining  the  ore,  so  that  t^e  actual  ooèt  of  the  copper  will 
be  oaly  the  metallurgical  treatment,  amounting,  as  already  âfated 
by  Mr.  Douglas'  estimate,  to  flve  and  onequarter  cents  per^ 
pound.  In  addition  to  this,  the  sulphur  can  be  made  a  source 
of"  profit  l^yits  conversion  into  "floar  sulphur  or  sulphuric 
acid.  '     ■  '  * 

'  And  it  bas  been  estimated  that  the  ore  csn  be  smelted  at  the 
mine  and  reflned  for  about  flve  cents  per  pound.  ^

REPORT  OP  Prof.  J.  D.  WHITNEY. 


To  R.  M.  Thompbon,  Ebq.,  ) 

Boston,   Mabs.         )       *' 
,Mt  Dear  Sir: 
■    I  hâve  made  a  hasty  inspection  of  the  "Hartford  Mine,"  near 
Sherbrook,  Canada,  and  ÎJeg  îeave,  herewith,  to  présent  my  re-« 
port  of  the  same  : —  •     "     " 

The  Iode  Is^^ontained  in  a  glossy,  piye-grained  slate,  befong-' 
ing  to  thfi  "Québec  Group"  of  the  Canadian  Qeological  Survèy. 
Portions  of  this  rock  (MsintegraBe-with  rapidity  when  etposed  to 
the  air;  other  portions  remain  flrm  and  solid.     8t)ecimèiis  of  the 
slate  hâve  been  found,  on  examinafion,  to  coytain  great  numbers^ 
of  small  crystals  of  -pyrites  ^jaseminateà  through  the  mass.     This^ 
rock  bbs  a  variable  strike,  being  much  twisted  in  its  stratiflcatioia. 
At  theinine  it  runs  nearly  east  and  west  and  dips  at  a  njoderate 
but  varying  angle  to  the  south.    tt  is  intersected  by  vertical  dykes 
of  eruptive  material  (metaphyr),  which  run  east  and  virest,  and  in- 
tersect  both  country  rock  and  Iode  without  much  disturbing 
either,  so  far  as  I  had  opportunity  to  observe.     When  the  dykes 
bave  branched  so  as  to  include  a  portion  of  the  Iode,  tlffs  retains 
its  natural  appearance.         ■  ^^

rouB  material  lying  pretty  nearly  in  the  plane  of  the  stratification 
or^amination  of  the  encloaîng  country  rock,  and  not  separated 
by  well-deflned  flucan  selvages  or  other  ordinarîly  observed  indi- 
cations of  a  prefixisting  fissure.  In  some  places,  however,  a 
tolerably  sniooth  wall  does  |xtend  for  some  distance  separating, 
or  indicating  a  séparation  between  the  Iode  and  the  countiy.  In 
gênerai,  the  outline  of  the  mâss  of  ore,  in  a  direction  at  right 
angles  to  the  run  of  the  Iode,  or  in  a  transverse  section  on  the  dip, 
is  very  irregular.  The  gênerai  character  of  the  ore  body,  however, 
is  that  of  a  flattened  mass,  dipping  Mjith  the  formation,  having  a 
length  along  the  strike  of  the  county  rock  of  from  one  hundred 
to  two  hundred  feet,  and  à  thickness  of  from  six  or  eightto  thirty, 
or  even  more,  feet.  This  mass  bas  been  foUowed  down  in  Shaft 
No.  6  as  far  as  the  eighty-flve-fathom  level,  and  the  character  of 
the  Iode  has  been  found  to  be  essentially  the  same  from  top  to 
bottom.  The  dip  averages  about  thirty  degrees,  and  is  in  a  south- 
erly  direction,  tlie  shaft  carried  down  on  the  dip  of  the  Iode 
having  almost  exactly  a  southerly  direction,  (magnetic,  the  varia- 
tion being  sixteen  degrees  west). 

Shaft  No.  5  appears  to  be  on  the  western  edge  of  the  ore 
body  ;  at  ail  events,  the  workings  hâve  been  entirely  confined  to 
the  région  east  of  No.  6.  It  would  look  as  if  the  ore  had  been 
eut  ofE  on  this  side  by  a  "fault"  or  heave  ;  but  I  was  unable  to 
assure  myself  that  such  had  been  the  case. 

Prom  the  best  information  I  could  obtain,  about  seventy- 
five  thousand  tons  of  ore  hâve  been  taken  from  this  mine,  which 
would  indicate,  as  the  average  dimensions  of  the  shoot  of  ore 
worked,  about  one  hundr^  fbet  in  length  by  ten  in  thickness.

The  character  of  the  ore  is  extremely  uniform  as  exposed  in 
the  mine.    It  is  a  vast  body  of  iron  pyrites,  with  a  small  per- 
centage  of  copper  contained  in  it,  and  almost:  or  quite  entirely 
free  from  any  admixture  of  gangue  or  vein-stone. 

It  is  a  metalliferous  mass  bf  very  remarkable  dimensions 
and  freedom  from  minerai  matter.  Unfortunately  its  ténor  in 
copper  is  net  high,  as  is  evidpmt  from  inspection.  Its  actual 
yield  could,  of  course,  only^ptold  after  assay,  as  low  grade 
copper  ore  cannot  ,be  estimated  with  any  approach  to  accuracy 
by  the  eye  alone.  It  is  said  to  hâve  yielded  by  tlie  "  Henderson 
Process,"  in  the  wet  way.  fouf-and-a-half  per  cent,  of  metallic 
copper,  on  the  average.  Spécimens  of  a  higher  grade  ore  were 
shown  me  as  having  come  from  the  part  of  the  mine  j»ow  undei; 
wster,  and  you  hâve  the  authority  of  Capt.  Bray  as  establishing 
the  fact.  ,  j 

The  inference  to  be  drawn  from  the  facts  observed,  and  the 
information  gathered  from  reliable  persons,  seem  to  be  that  there 
is  hère  a  very  large  body  of  low-grade  copper  ore  which  bas 
been  already  worked  to  a  considérable  depth,  and  which  is  likely 
to  hold  for  a  considérable  distance  downwards.  Several  consid- 
érations support  this  viéW.  In  the  fltst  place,  the  ore-body  is  so 
large  that  it  would  seem  to  be  highly  improbable  that  it  should 
come  to  a  sudden  tennination.  In  the  next  place  it  would  ap- 
pear  from  the  facte  gathered  that  where  the  Une  of  the  "Crown" 
properly  crôsseB  tfie  Iode  (which  in  the  shaf  t  is  a  little  below  the 
seventy-three-fatho^  level),  thera^is  no  falling  off  in  the  dimen- 
sions of  thjB  mass;  but,  if  anything,  an  increase,  the  workings 
being  fully  two  hu^dred  feet  long  on  the  Une  of  the  "Crown" 
property.  /

Had  not  the  weather  and  an  accident  prevented  my  making 
an  examination  on  the  Une  of  outciop  ortlie  Iode,  I  shoujd  hâve 
got  additional,  and,  I  présume,  valuable  testimony  as  to  its  charac- 
ter  for  permanence.  The  lo(ie  is  said  to  liave  an  extensive  linear 
development,  and  that  I  j^hould  regardas  an  important  élément  in 
judging  of  its  holding  in  depth.  It  has  alsô  become  a  question 
whether  there  are  not  other  chimnies  or  shoots  of  ore  on  the  Iode, 
of  extent  and  value  enough  to  be  worked.  and  which  may  be 
richer  in  copper. 

The  question  seems  to  be  narrowed  to  a  mctallurgical  one; 

namely,  whetlier  a  low  grade  copper  ore  occurring  in  large  quan- 

tities,  and  under  very 'favorable  conditions  for  being  cheaply 

mined,  can  be  worked  with  profit.     It  is  also  fairly  to.  be  con- 

sidered,  in  this  connection,  that  the  ore  may  increale  in  richness 

as  indicated-  by  the  Qccurrence  of  a  better  grade  near  the  bottom 

of  the  mine  than  any  which  had  been  previously  found. 

Not  being  an  authority  in  metallurgy,  and  having  only  a 
superficial  knowledge  of  that  subject,  I  do  not  feel  compétent  to 
give  any  opinion  on  the  possibility  of  working  an  ore  which  has 
yielded  four  and  a-half  pcr  cent,  by  the  Henderson  Process,  nor 
do  I  know  how  much  has  been  lost  in  this  process;  that  is,  how 
much  the  real  percentage  of  tlie  ore  is. 

As  ore  not  averaging  over  one  and  a-half  per  cent,  of  copper 
is  successfuUy  treated  in  Europe,  it  would  seem  that  the  ore  of 
the  Hartford  Mine  ought  to'  pay  a  respectable  profit  when  treated 
by  an  economical  process.  The  facilities  for  opening  and  work- 
ing the  "mine  so  as  to  produce  a  large  quantity  o^  ore  at  a  low 

cost,  are  certainly  very  great. 

Very  respectfully  yours,

REPORT  OF  CAPT.  BRAY. 


Robert  M.  Thompson,  Esq. 
Sec.  Orf&rd  Nickel  and  Copper  Go. 
Boston,  Mass 

Dbar  Sir: 


•I 


I  am  in  due  receipt  of  your  favor  of  the  16th  inst.,  request- 
ing  me  to  answer  certain  queries  on  the  subject  of  the  mining 
property  in  this  neighborhood  known  as  the  Crown  Mine. 

Query  FtV«<.— The  probable  cost  of  openingand  workingthe 
said  mine  through  the  présent  shaft  known  as  Shaft  No.  5  of  the 

Hartford  Mine. 

Answered.— This  opération  would  be  simply  a  continuation 
of  the  Works  at  this  shaft  in  the  same  style,  or  nearly  so,  as  they 
were  conducted  when  thfit  shaft  was  sunk  to  its  présent  depth  by 
the  C.  C.  and  S.  C.  L.  of  Glasgow. 

It  would  he  necessary  to  sink  this  shaft  to  a  depth  of— say 
thirteen  fathoms,  and  to  exteiid  a  drift  eastwardfrom  the  bottom 
80  attained  for  a  distance  of  about  twenty  fathoms,  or  so  far  as 
would  be  permitted  by  the  state  of  ventilation  in  the  mine;  and 
to  this  end  it  would  be  necessary  to  arrange  with  the  above-men- 
tioned  Co.  to  be  enabled  to  sink  a  winze  from  the  eighty-flvc-fathom 
level  at  a  point  where  this  is  intersected  by  the  boundary  Une  be- 
tween  the  two  properties;  this  last  would  be  sunkto  the  same  Jer-' 
el  as  would  be  attained  by  Shaft  No.  5,  and  the  tw>béing  con- 
nected  by  the  above-mentioned  drift  would  opeirlîp  a  block  of  ore- 
gtonndtwelve  fathoms  deep  by  twen^/jiatliomB  in  length.which,  if  it 
èhould  prove  to  be  as  prodîietifeas  a  like  block  in  the  mine  of

Hartford  in  the  level  above,  would  tum  out  about  twelve  thou-

by  seven  feet.  containing  anareaof  ninety-eight  square  feet  would 
average  one  hundred  and  thirty  dollars  per  fathom  lineal

The  cost  of  sinking  the  winze,  with  an  area  of  flfty-four 
feet.  would  be  seventy-flve  dollars  per  fathom,  lineal  measure- 
ment. 

And  the  cost  of  driving  the  drift  containing  a^a  of  forty- 
two  feet,  would  be  from  sixty-flve  to  seventy  dollars,  lineal

In  opening  through  No.  5  Shaft  and  winze  from  the  eighty- 
flve-fathom  Jevel,  moderate  returns  would  be  immediately  made^ 
as  there  is  a  small  block  of  ore  already  opened  at  tlie  angle  the 
Shaft  No.  5  makes  with  the  eighty-flve-fathom  level,  which  lies 
within  the  Crown  Mine  limits,  and  is  ready  for  stoping;  this 
would  produce  aitogether,  about  eight  huudred  tons  of  ore,  (800), 
^e  shaft  is  fast  leaving  the  dip  of  the  ore  body,  and  probably 
■fîll  soon  be  aitogether  out  of  it.  After  sinking  about  six  fath- 
oms  deepcr  tbah  the  présent  bottoni,  unless  a  change  should  lake 
place,  no  returns  can  be  counted  oafrom  this  point. 

The  winze  would  go  d^^wn  m  a  strong  body  of  ore,  and  ought 
to  produce  from  seventy  to  eighty  tons  of  good  ore  from  each 
month's  sinking  of  three  and  a-half  or  four  fathoms. 

After  the  first  block  of  ore  is  opened  out,  there  would  be 
nothing  toprevent  the  monthly  output  commencing  at  four  hun- 
dred  tons  (400),  in  a  few  months  reaching  one  thousand  (1,000), 
by  which  time  the  second  block  would  begin  to  make  returns,  in 
fact,  after  two  years'  work,  during  which  timc  thore  would  be  a 
gradually  incr«asing  scale  of  returns.  I  seè  no  reason  to  doubt 
that  the  mine  could  be  put  into  a  condition  to  return.  if  re- 
quired,  two  thousand  (2,000)  tons  of  ore  per  month  without  over- 
straining  its  capacity. 

Qtury  Foum.—Give  in  each  case  the  expense  of  opening  the 
mine  read^  for  work,  specifying,  &c. 

An»u)er«d.—The  particular  opérations  for  opening  the  mine 
to  a  certain  extent,  and  the  «xpense  attending  them.  hâve  been 
already  detailed. 

The  cost  of  minmg  the  pre.  after  the  mine  is  opened,  by 
either  of  the  above-mentioned  methods,  would  not  vary  materi.

'  ally,  and  may  be  set  down  in  round  numbers,  for  ail  mining  ex- 
penses.  at  three  dollars  per  to^,  ànd  tbe  loss  in  materials 
will  throughout  tlie  year  be  about  ten  per  cent,  on  the  total  out- 
^  lay.  In  the  case  of  working  by  contract,  the  contractors  repay 
the  value  of  nearly  ail  the  materials  they  use,  with  which  they 
are  sùpplied  by  the  Company  at  a  flxed  price.  * 

Query  Mfth.T-State  from  your  past  expérience,  &c..  what 
percentàge,  &c.  \V, 

Antwered. — For  the  ïàst  three  years  the  Hartford  Mine  was 
worked,  about  sixteeu  per  cent,  of  the  total  output  was  elimi- 
nated  to  bring  the  ore  to  the  percentàge  required  at  the  Ëxtract- 
ing  Works  ;  thia  rejected  portion  consisting  of  two-thirds  ôf  poor 
rock  and  the  remaining  one-third  of  ore  rich  in  sulphur,  but  con- 
taining  only  from  one  to  two  per  cent,  of  copper;  this  last  pro- 
duct  was  sold  under  contract  at  three  dollars  per  ton  delivered 
at  the  station  on  the  cars.    '" 

A3  the  deposit  of  ore  âas  steadily  though  slowly  improved  in 
quality  between  the  flfty  and  eighty-flve-fathom  levels  in  the 
Hartford  Mine,  and  as  it  now  contains  little  or  no  unproductive 
rock  mixed  with  it,  tbe  quantity  to  be  rejected  would  be  rather 
less  than  above  stated,  te  bring  the  ore  to  an  average  of  five  per 
cent,  of  copper  by  wet  assa^,-and  this,  by  careful  manipulation, 
\^  ought  to  produce  ip  actual  fine  copper  four  per  cent. ,  or,  say,  one 
\ton  of  fine  copper  to  every  twenty-ûve  tons  of  ore  delivered 
t  the  WorlSfl. 

\     The  average  of  sulphur  in  the  rejected  ore  was  from  thirty- 
eigÊt  to  forty  per  cent. ,  and  on  this  basis  it  was  sold. 

I  do  not  think  the  better  class  of  ore  was,  as  a  gênerai  rule, 
fusaVed  for  sulphur;  if  U  was,  it  never  came  to  my  knowledge.

It  will  appear  clear  to  you  that  this  property  of  the  Crown 
Mine  is  altogether  removed  from  the  common  run  of  mining 
spéculations,  considered  as  such.  Hère  the  ore  body  is  known  to 
exist,  its  bulk  known  to  a  certain  extent,  and  its  economical 
value  acknowledged.  only  requiring  skillful  management  in  the 
réduction  as  well  as  in  the  mining  department,  to  inakeit  such  a

of  C{(nadian  copper  mines.

kve  Invented  an  Improved  Process  for  Separating  Sulphur  froœ 
I  Ores,  of  which  t^e  followiiig  is  a  spèciflcation  : 
By  thia  inrention,  and  the  mafioer  of  working  it  as  herein 
.  described,  the  jiydrog&n  sulphide  koay  be  produced  in  large  quan- 
tlties  at  the  smallest  possible  cost,  and  witl»  the  mtoimum  of  la- 
bor.  &Y  the  intermlngllng  of  tbis  gas  wHh  the>*ulphurou8  acM 
from  the  oxidatiop  of  the  sulphides.  the  sulphur  is  effectuaUy 
precipiteted  in  a  condition  alniost  free  from  impurities. 

I  am  also  awi^rethat  the  suiphurous  acld  frpm  the  roasting 
of  suiphurous  oresjias  bcen  extënsively  utilized  by  converting  it 
into  sulphuric  acld;  but  this  method  is  not.  as  a  rule.  economi- 
cally  avallable,  ad  mines  are  frequently  situated  remote  from 
manufacturing  centers,  and  the  transportation  of  the  acid  js  ex- 
periKlve,  both  in  packages  and  freight. 

Sulphur.  on  4he  other  hand.  is  easily  handled,/require8  no 
expensive  packages,  and  can  be  transported.  withoqt  danger,  to 
remote  markets.

cendensed,  if  desired,  in  thé  chimney  or  tower  d,  which  is  fliled 
with  coke  or  other  perméable  material,  and  kept  moist  by  water 
introduced  at  top.  This  water  may  be  used  over  and  over  again 
until  it  absorbs  sufflcient  acid  to  be  useful  in  some  other  process. 

A  fire  having  been  kindled  on  the  grate-bârs  e,  fuel  is  pût 
on  until  the  kilns  are  thoroughly  heated.  The  ore  is  then  filled 
in,  and  if  it  contAins  above  sizteen  percent,  of  sulphur,  then 
the  beat  generated  by  the  burning  of  the  sulphur  will  bç  suffl- 
cient to.  maintain  the  combustion,  and  no  other  fuel  will  be  re- 
quired.  The  sulphur,^  it  is  bumed.' passes  into  the  common 
flue  b  iA  the  shape  of  sulphurous  acid.  When  the  ore  is  in  a 
State  of  combustion — say,  at  a  red  beat — the  air  is  shut  off  and 
superheated  steam  is  admitted  through  the  pipe  t,  forming  sul- 
phureted  hydrogen,  which,  meeting  and  intêrmingling  with  the 
sulphurous  acid  from  the  adjofning  kiln,  causes  th«  wellknown 
chemleal  reaction  already  described  to  take  place,  and  the  sul- 
phur' is  set  free. 

For  the  better  and  more  regular  working  of  the  process,  it  is 
found  préférable  to  supply  each  kiln  or  pyrites-bumer  with  air 
and  steam  alternately,  so  that  while  one  is  producing  sulphurous 
acid  àuother  one  is  producing  hydrogen  sulpbide.  At  regular  in- 
tervais the  opération  is  rever^ed,  air  being  shut  off,  and  super- 
heated steam  being  then  supplied  to  one,  while  iathe  other  the 
steam  is  shut  off  and  air  supplied.  Where  kilns  are  constructed 
in  parallel  rows,  back  to  back,  the  superheated  steam  and  air 
may  be  controUed  by  one  valve  for  each  row,  so  that  each  row  of 
kilns  may  be  producing  sulphurous  acid  and  sulphureted  hydro- 
gen alternately,  and  tbus  yield  a  steady  fiow  of  the  desired  gases.

When  the  ore  is  rich  enough  in  sulphur,  and  the  air  and  sti- 
perheated  steam  are  properly  controlled,  they  may  be  introduced 
simultaneously  and  continuously  into  the  kiln?  or  pyrites-bumer, 
and  the  sulphurous  acid  and  sulphureted  hydrogen  may  b^  pro- 
duced  in  such  manner  as  to  cause  the  reaction  to  take  place,  as 
aiready  described.  In  so  doing,  it  is  found  préférable  to  admit 
the  air  at  the  bottom,  and  the  superheated  steam  nearer  or  at  the 
top.  A  stream  of  moist  steam  is  admitted  through  pipe  m  into 
the  flue  b,  so  that  the  f ree  sulphur  aiready  formed  may  be  pro- 
tected  from  burning  by  any  air  which  may  find  its  way  in. 

Some  of  the  sulphur  will  be  collected  in  the  flue  and  cham- 
ber,  while  the  remainder  will  be  carried  out  by  the  water,  and 
pr^ipitated  in  tanks  pr  other  suitable  vessels. 

If  the  ore  or  sulphur-yielding  substances  are  being  roasted 
or  bumed  in  revolving  or  reverberatory  fumaces,  worked  in 
pairs,  the  same  method  may  be  employed  by  altemately  intro* 
ducing  air  and  superheated  stéam,  and  mixing  the  resuUing  gases 
in  a  common  flue  or  chamber,  as  aiready  described.  If  working 
a  single  fumace,  a  stream  of  highiy-superheated  steam  may  be 
continuously  admitted,  preferably  along  with  heated  air,  and  so 
regulated  that  the  proper  proportion  of  gases  may  be  produced. 

An  ezcess  of  air  is  to  be  avoided.

by  the  résignation  of  one  of  tbe  présent  directors. 

Tlie  property  of  thé  Conipany  consista  of  the  Orford  Nickel 
Mine;  the  Crown  Copper  and!  Sulphur  Mine;  and  two  patents

for  ptocesses  for  roastiiig  copper  ores,  and  the  Leckie  Sulphur 
Patent.  The  Company  is  organized  under  a  spécial  charter  from 
the  Par^ament  of  Québec,  which  exempts  stockholdefs  from  ail 
liability.  Its  capital  stock  is  $300.000,  divided  into  lîi^OOO  shares 
of  thé  par  value  of  $20.  $25.000  bas  already  been  paid  in  for 
the  worklng  capital  of  the-^ickel  Mine.  The  Company  now 
desires  to  raise  $125,000  additional  to  complète  the  payments 
for  the  Crown  Mine,  erect  extraction  works,  and  for  working 
capital. 

To  raise  this  sum,  the  Company  oflfers  iu  stock  at  par, 
preferring  this  method  to  putting  out  a  larger  number  of  shares 
and  selling  them  at  a  great  discount. 


In  the  developement  of  the  property,  two  plans  hâve  been 
considered: 

'K    -  — 

First,  to  lease  from  the  owners  of  the  Hartford  Mine  the 
présent  shaft;  and  to  put  up  such  part  of  the  smelting  works  as 
wll  be  necessary  to  treat  the  ore  produced.  Under  this  plan  the 
e^ense  for  the  âi$t  year  will  be  :  <s 

V       P^ypent  of  balance  due  on  mine $20,000  00 

Sinking  shaft  and  running  levels.  .• T^SOO  00

Salaries  and çeneral  expenses ,,,',  lo'ooo  00 

Working  capital  for  carrying  on  smelting. . . .  20,000  00 

'^^*^ $84^50000 

At  least  6.000  tons  of  ore  can  be  delivered  during  the  ôrst 
year,  and  this  will  yield:  ' 

COPPBB,  222  tonii,  or  498,280  pounds.  A  part  of  the  cost  of 
which  is  included  in  the  above  expenditures,  but  allowing

half  the  rate  of  profit  claimed  when  the  works  are  ' 
atfuUwork.    The  return  will  be 12  000  00

io  complète,  the  works  will  reqiiirè 68  000  00 

Leaving  working  capital .$26  000  00 

Which  should  be  inçroased  from  the  earnings  of  the  second 
year  to  $100,000,  additional  stock  being  issued  tq  represent  it, 
and  tbus  increasing  the  capital  to  $400,000.  ^!PAe  promotèrs,  itftJr 
ewrtful  emmination,  are  conmnced  t/iat  tfu  abote  plan  ean  de  ear- 
ried  oui,  that  is,  in  'substance,  Ihat  on  a  cash  advance  and  guar- 
anty  of  $125,000,  the  mine  will  in  two  years  pay  the  expenses  of 
its  own  developement  and  érection  of  extraction  works. 

the  second  plan,  which  must  be  adopted  if  ahaft  No.  5  can- 
not  be  leased,  diflfers  from  the  first  onlyin  the  time  and  cost  . 
necessary  lo  sink  a  vertical  shaft,  say  406  feet.    The  time  re- 
quired  for  this  will  be  about  eight  months,  and  the  cost  $10,000 
to  $12,000.    After  the  shaft  is  down,  there  will  be  some  time  - 
and  money  saved  in  developing  the  mine,  and  the  work  of  pay- 
ing  for  the  mine  will  take  two  and  one-half  instead  of  two  years. 
The  person  who  now  invests  in  the  stock  will,  we  believe, 
receive  within  two  years  thlrty-three  per  cent.  irfÇcrip  dividends 
and  ten  per  cent,  in  cash;  and  thereaf ter  tin  his  stock,  dividepds

The  objectof  this  circulafiB  to  provoke  investigation.  It 
does  not  attempt  to  answer  ail  questions  that  may  be  asked,  but 
bycâlling  at  our  office,  4  Pemberton  Square,  and  talking  with 
one  of  the  undersigned,  any  further  information  you  may  désire, 
and  every  opportunity  for  full  investigation  will  be  given. 

We  understand  that  in  asking  Boston  investors  to.  take  hold 
of  a  Canada  Copper  mine  we  will  be  at  a  great  disadvantage  on 
account  of  the  ill  success  of  Boston  speculators  in  Canada,  but 
we  do  not  regard  our  présent  oflfer  as  a  spéculation,  but  as  a 
legitimate  business  enterprise— an  enterprise,  toycsure,  inwhich 
there  is  risk,  but  the  risk  is,  we  belieye,  reduc«!d  to  a  minimum, 
and  the  enterprise  only  needs  good  business  pnanagement  to  in- 
sure success.  „  /
